Backcross: The Past, Present and Future of American Chestnut

Forestcast

A hundred years ago, the American chestnut was the redwood of the East. It was big, and it was everywhere, especially in the southern Appalachians. But, today, it’s just a shrub and is, functionally, extinct.

With chestnuts having gone through such a dramatic decline, restoration has been a priority, and it’s been a restoration effort unlike many others. It’s been one of the most passionate efforts an American tree has ever seen.
